This is the beginning of the Eva Hat knitting pattern by Yelena Chen.
This is going to be a chemo cap for my mother-in-law, who is battling cancer. The ribbing portion is shaped like the symbolic ribbons used to draw attention to various causes, and the teal color represents her particular cancer.
If you're knitting one of these for a cancer patient who is near and dear to your heart, you can use yarn in whichever color best symbolizes their particular cancer. The symbolism is subtle, and the hat can work for males or females.
